BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematisof hybrid origin and will be referred to hereafter by its cultivar name‘Zo14100’. ‘Zo14100’ is a herbaceous perennial grown for use as alandscape plant.

The Inventor discovered the new cultivar in August of 2014 as anaturally occurring whole plant mutation of Clematis ‘Tangutica’ (notpatented, used in the trade as a cultivar even though it is also thespecies name) in a seedling block at a nursery in Boskoop, TheNetherlands. The seedling block had been sown with seed collected fromnumerous seedling plants of Clematis ‘Tangutica’, therefore the exactparent plant is unknown.

Asexual propagation of the new cultivar was first accomplished bysoftwood stem cuttings under the direction of the Inventor in Boskoop,The Netherlands in 2015. Asexual propagation by softwood stem cuttinghas determined that the characteristics of the new cultivar are stableand are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish Clematis ‘Zo14100’ as a unique cultivar of Clematis.

-   -   1. ‘Zo14100’ exhibits a dwarf plant habit.    -   2. ‘Zo14100’ exhibits a non-climbing habit.    -   3. ‘Zo14100’ exhibits a very floriferous blooming habit.    -   4. ‘Zo14100’ exhibits cold hardiness at least to U.S.D.A. Zone        5.

The potential parent plants of ‘Zo14100’ all differ from ‘Zo14100’ inhaving a climbing plant habits and in being less floriferous. ‘Zo14100’can be most closely compared to the Clematis cultivars ‘Kugotia’ (U.S.Plant Pat. No. 10,952) and ‘Bill MacKenzie’ (not patented). Both aresimilar to ‘Zo14100’ in having yellow color flowers and in coldhardiness. Both differ from ‘Zo14100’ in being taller in height with aclimbing habit and in having flowers that are larger in size with darkpurple stamen connectives.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearanceand distinct characteristics of the new Clematis. The photographs weretaken of a two-year-old plant as grown outdoors in a 2-liter rosecontainer in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a view of ‘Zo14100’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers andseed heads of ‘Zo14100’.

The photograph in FIG. 3 provides a close-up view of a cross section ofa flower of ‘Zo14100’.

The colors of the photographs are as close as possible with the digitalphotography techniques available, the color values cited in the detailedbotanical description accurately describe the colors of the newClematis.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of two-year-old plants as grownoutdoors in 2-Liter rose containers in Boskoop, The Netherlands.
